On the 24th, the South Korean stock market experienced Fluctuation, with the composite stock price index KOSPI rising by 14.03 points to 4,131.35 points, mainly driven by net purchases from individual and institutional investors. The KOSDAQ index, on the other hand, fell slightly by 0.10%. The Korean won depreciated against the US dollar, and gold prices rose.

The content that received the highest response in the community the previous day was the questioning of whether the sharp fluctuation in the exchange rate during the early morning hours was due to the Korean won's defense process. Beyond merely sharing the exchange rate figures, concerns about the potential transfer of fluctuations in the forex market to overall risk assets continue to emerge. Some investors are following the trend of the exchange rate as it may become a leading indicator that suppresses domestic investment sentiment.
Interpretation of the dramatic changes in the Exchange Rate and attempts to relate them to the macro environment
In the context of the rapid fluctuations of the Korean Won to US Dollar Exchange Rate, various interpretations have been proposed. The content that links the reasons for the fluctuations to changes in the global financial environment, geopolitical tensions, and uncertainties in political diplomacy has received significant attention, surpassing discussions on short-term supply and demand issues. In particular, as news related to the evacuation of diplomats' families and other international situation reports are mentioned, the market has also shown reactions reflecting risk aversion sentiment.

The French state postal service, La Poste, and its banking subsidiary, La Banque Postale, suffered a large-scale distributed denial-of-service attack on the eve of the Christmas holiday, resulting in a complete outage of online services. This rendered the website, mobile applications, email inquiry systems, and even the digital storage platform Digiposte all unusable, and online banking services were effectively interrupted, causing great inconvenience to millions of users.
On the day of the attack, La Poste stated that the collection and delivery of physical mail were still in operation, and core financial functions such as ATMs, in-store card payments, and SMS verification transfers were also operating normally. The company specifically emphasized that customer personal information was not compromised. However, there have been actual service disruptions such as delays in parcel collection and delivery and temporary closures of some post offices, leading to growing dissatisfaction among consumers.
The French prosecution has officially launched an investigation into this incident, but the mastermind behind the attack has yet to be identified. Observers have pointed out that, given the situation in Europe, with

Global workflow automation company ServiceNow has officially announced its acquisition of internet of things security startup Armis for $7.75 billion (approximately 11.16 trillion Korean Won). The transaction will be conducted entirely in cash, with the acquisition price reflecting a premium of about $1.5 billion over Armis's valuation during the investment round in November last year, which included participation from CapitalG, a growth investment fund under Alphabet.
Armis provides technical protection against cyber attacks for various connected devices (such as industrial robots, office printers, etc.) through a security platform called Centrix. Traditional security solutions typically collect data by installing agents within the system, whereas Armis uses an agentless approach to detect connected devices and identify potential threats, and its differentiated technological competitiveness has been recognized by the industry.
ServiceNow plans to expand its network through this acquisition.

The crypto assets market is showing a volatile trend, with the trading price of Bitcoin (BTC) at 129,650,000 Korean Won, down 2.56% from the previous day, with the decline slightly easing.
Bitcoin has fluctuated between 130 million and 135 million Korean won in the last 24 hours, adjusting due to its inability to break through the 90 million won (USD benchmark) resistance level. Since entering the fourth quarter, it has fallen over 22%, continuing its weakness, which is considered one of the worst year-end performances aside from the major bear market.
Against this backdrop, analysis indicates that the weakness of the US dollar index may become a positive factor for Bitcoin. Another situation worth noting is that, although asset management company BlackRock has listed Bitcoin ETFs as a major investment theme, the recent outflow of funds from spot ETFs is exacerbating market uncertainty.
The trading price of Ethereum (ETH) is 4.34 million KRW, down 4.06% from the previous day; Ripple (XRP) is reported at 2789.

As enterprises introduce artificial intelligence ( AI ) to build autonomous work environments, the control permissions and security management of AI agents are becoming core issues in digital operations. In particular, highly advanced AI agents can execute tasks or make business decisions on behalf of user identification. Once security is breached, it could lead to the worst-case scenario where the entire organizational system is under control.
Rubrik co-founder and CEO ( CEO ) Bipul Sinha ( recently emphasized in an interview: "In an era where agents handle business at superhuman speed, damage can occur tenfold in just ten minutes." He pointed out that the traditional security system struggles to manage 'agent governance', which is emerging as a new means of control. He explained: "AI agents operate business processes like humans and can sometimes even mimic user identification, thus possessing 'superhuman' attributes."
To enhance agent security, Rubrik has launched

The malicious code "sandworm(Shai Hulud)" targeting the JavaScript development ecosystem continues to evolve, with the level of software Supply Chain attacks confirmed to have further improved. The latest analysis shows that this malicious code has surpassed the previous level of merely infiltrating individual software packages, enabling it to transform developers into unwitting and continuously spreading carriers, possessing a system for automatic diffusion.
According to a report released by the security firm Expel, a recent variant of the Sandworm has the capability to automatically infect developer environments and spread through the npm registries they manage. This malicious code executes an npm package implanted with a virus during the installation phase, infecting the program in two steps. First, if the "Bun" JavaScript runtime is not installed in the target environment, it will be installed automatically; subsequently, through a complex obfuscated payload, it induces credential theft, data leakage, and reinfection in the background.

The Bank of Japan (BOJ) decided to raise the policy interest rate by 25 basis points from 0.5% to 0.75% at the monetary policy meeting held on December 19, 2025. This is the second interest rate hike by the BOJ since January of this year, and the interest rate level has reached its highest record since 1995.

The resolution was passed with a unanimous vote of 9:0, fully in line with market expectations. The 50 economists interviewed beforehand all predicted this interest rate hike, marking the first time under Governor Ueda's tenure that there has been a "unanimous" expectation for an interest rate increase.


The Governor of the Bank of Japan, Kazuo Ueda, pointed out at a press conference that short-term interest rates being at a 30-year high has no special significance, and the authorities will closely monitor the impact of interest rate changes. He stated that the current distance from the neutral interest rate range.

At the end of 2024, the Bitcoin market experienced a textbook-like macro shock. Under the expectation of interest rate hikes by the Central Bank of Japan, over a trillion dollars in "Yen Arbitrage Trading" began to Close Position globally, causing the price of Bitcoin to fall by more than 5% within 48 hours. This event revealed a profound change: Crypto Assets have become a part of the global Liquidity chain, and their price Fluctuation is increasingly driven by complex TradFi mechanisms. For developers and tech practitioners, waiting for traditional financial analysis has become outdated, while expensive professional terminals are out of reach. Fortunately, the maturity of current Open Source large language models and localized deployment technologies empowers us to build our own real-time AI-driven analysis engines. This article will detail how to start with hardware selection, choose and optimize a dedicated financial analysis model, and design a complete workflow capable of automatically processing news, interpreting data, and outputting structured risk warnings.

The year 2025 is undoubtedly filled with contradictions and controversies for Ethereum. Despite endorsements from major influencers, various DATs, numerous technical upgrades, and hacker promotions, the performance in the secondary market has been disappointing: Ethereum finds itself in an "awkward" middle ground: in terms of asset attributes, it seems to lack the pure commodity attributes and safe-haven consensus of Bitcoin as "digital gold"; in terms of technical performance and fee capture, it faces fierce competition from high-performance chains like Solana and Hyperliquid, which appear to align better with investors' preferences and valuation models. Moreover, the Dencun upgrade in 2024 did not restore Ethereum's former glory, but rather became a nightmare that devoured the narrative.

When "zkEVM achieves real-time verification, reducing proof latency from 16 minutes to 16 seconds" is mentioned repeatedly, it is often understood as a mere performance improvement. However, in the zk framework, time is not a neutral metric.
The magnitude of the delay directly determines whether the zkEVM can enter the timing critical path of the system, thereby changing its role in the architecture.

16 seconds is not just "faster", but it is the first time that zk proofs have been brought into the time scale close to the block slot. This step has fundamentally different implications for L2 zkEVM and L1 zkEVM.

On L2 zkEVM: From "Post-Finality" to Slot-Level Trustworthy State

In L2 zkEVM, the function of zk proofs is to provide
